Burn – one of the most dangerous injuries to the body. Factor plays an important role and degree of burn size (household burns, burns, severe). Depending on the level assigned to the appropriate medical care. Burn – this is tissue damage under high temperature or chemicals. They come in four vidov.himicheskie burns, electric burns, thermal burns, radiation burns.

Experts estimate the seriousness of the burn area and depth of damage. What these figures is less than the faster and easier to burn heals. In order to measure the surface of the damaged section, enter the following standard. It is known that the hand of man is a percentage of the surface of his body. To determine the proportion of the damaged surface of the human body decided to allocate 11 segments of 9 percent (the so-called rule of "nines"). So, each arm is 9 percent of the total body, a leg – 18, face and neck – 9 and so on.

Thermal damage to the covers are most common, often accompanied by thermal inhalation injury (TIT), combinations with mechanical trauma. Heat damage includes heating of tissue above the critical level – 45oS. This is accompanied by denaturation of proteins. Tissue damage is the total derivative of heat and is characterized by a view (source) of the thermal agent, the duration of his and thermal conductivity of the tissue. Hydrophilic human skin has a high specific heat and low thermal conductivity (so the skin is overheated very slowly, but slowly and cooled). Thus, thermal damage continues even after, when the thermal agent has been extinguished or removed (this is of great importance in terms of first aid). Dead as a result of the thermal factor superficial tissues are said to burn scab. A slight warming of the skin (up to 60 C) leads to the formation of wet (kollikvatsionnogo) scab. A more significant warming of the skin formed a dense dry (Coagulation) scab. The degree of density and thickness of the crust can be different (depending on temperature, exposure, exposure, etc.) Burn wound – a three-dimensional mass of damaged tissue. On its edge is determined by the congestion zone, and center – the area of coagulation. The intermediate zone – a zone or a zone of stagnation paranecrosis, so named because it becomes a static circulation. As a result, the thermal effect of the microcirculatory bed in this area fixed red blood cells and mikrotrombov. Depending on the depth of destruction are following the severity of burns: I degree (minor burns) – redness, pain and minor swelling of the skin; II degree (mild burn) – severe pain at the site formed a burn blisters filled with fluid; III degree (severe burns) – necrosis and peeling of the skin. Pain with weak or absent, since the nerve endings are destroyed; IV degree (very severe state) – the destruction of not only the skin but also the deeper tissues and even bones. First aid for burns 1. If possible, remove all clothing covering the burned body surface. It can only cut and not removed. 2 burnt place with oil or alcohol. You can not pull anything that is stuck to the surface of the burn. 4. If there are bubbles, puncture, or delete them. Protect their cotton-gauze bandage, taking care not to put pressure on the sore spot, where the fiber wool should be fairly thick. 5. If you have already broken through the bubbles, cover with a sterile bandage them, and put the top layer of cotton and secure. Further to accelerate tissue repair using Polimedel.
